Box with inwardly tapering guide cones for universal wind package with radial pay-out

ABSTRACT

A package for a wind of flexible material wound with a universal wind but having a radial opening into the axial opening through which the inner end of the material is brought out is enclosed in a box having end-forming flaps hinged about axes perpendicular to the axial opening of the wind. The coils being pulled off of the interior of the wind are controlled by inwardly tapering members, such as truncated pyramids, projecting inwardly from the end walls. These pyramids are formed by the folding of a blank of cardboard, which has extending flaps which are interengaged with the end flaps of the box to hold the pyramids in position.

57 ABSTRACT A package for a wind of flexible material wound with auniversal wind but having a radial opening into the axial openingthrough which the inner end of the material is brought out is enclosedin a box having end-forming flaps hinged about axes perpendicular to theaxial opening of the wind. The coils being pulled off of the interior ofthe wind are controlled by inwardly tapering members, such as truncatedpyramids, pro jecting inwardly from the end walls. These pyramids areformed by the folding of a blank of cardboard, which has extending flapswhich are interengaged with the end flaps of the box to hold thepyramids in position.

2 Sheets-Sheet l BOX WITH INWARDLY 'IAPERING GUIDE CONES FOR UNIVERSALWIND PACKAGE WITH RADIAL PAY-OUT PRIOR RELATED APPLICATIONS ApplicationSer. No. 8 19,777, filed Apr. 28, I969 shows broadly the use, of conesterminating adjacent the radial opening in a wind of this nature.

BACKGROUND OF THE INVENTION 1. Field of the Invention The inventionrelates to packages of flexible material of a universal type having aradialopeningthrough which the inner end of the material is led out fortwistless payout.

2. The Prior Art Taylor U.S. Pat. No. 2,767,938 shows a package offlexible material formed of layers each composed of a plurality ofFlG.-8s, with the free inner end of the material led out through aradial opening.

Taylor U.S. Pat. No. 2,828,092 shows a wind in which the inner surfacesof the end portions of the internalsurface of the axial opening arefrusto-conical and are supported during handling by short conicalmembers extending partly into the package.

As is explained in application Ser. No. 819,777, packages of the typeshown in the Taylor patents referred to have proven satisfactory fortwistless payouts at low speeds. However, at high speeds there appearsto be no way to insure that, in the course of a payout of substantialyardage from such packages, a working loop will not half-hitch a looseloop before the payout through the hole is effected. This results ininterference with a smooth payout of the material, and may stop italtogether.

The prior application Ser. No. 8 I 9,777 discloses the control of thecoils within the wind by the use of conical inserts into the ends of theair core which almost meet one another or meet one another withseparable contact opposite the position of the radial hole and whichperform a function which prevents the half-hitch from forming and yetdoes not provide significant resistance to payout if the surfaces of thecones are smooth at all points.

SUMMARY OF THE INVENTION The present invention is directed to a packagewhich conveniently provides these controlling inwardly tapering membersfor a wind of the nature set forth, and particularly, which provides ablank which can be stamped from cardboard and which after assembly canbe interleaved with the end flaps of a box in which the wind is placedso as to provide a convenient package in which the material is guided bythe cones during the withdrawal.

BRIEF DESCRIPTION OF THE DRAWINGS In the drawings:

FIG. 1 shows a blank from which the tapering members areformed;

FIG. 2 shows a plan view of the blank in assembled position ready to beplaced in the box;

FIG. 3 is a top plan view of the box with one pair of end flaps foldedoutwardly and the assembled blank of FIG. 2 in position;

FIG. 4 is a cross-section on the line 4--4 of FIG. 3, with the end flapsfolded in; 7

FIG. 5 is a cross-section on the line 5-5 of FIG. 3;

FIG. 6 is a plan view of the box with the outer flaps operated.

Referring now to FIG. I, the blank shown therein is composed of aplurality of portions 2 composed of frustra of triangles, with similarinward extensions 4 and outward extensions 6 and 8. The members 4terminate short of the center of the blank, leaving a space 10. Thelines separating the members 2 and 4, and separating each member 2 or 4from its adjacent member, and separating members 2 from members 6 and 8are provided with crease or fold lines indicated by the broken lines inFIG. I. The members 6 and 8 are separated from each other by cutsrepresented by solid lines.

The members 6 are constituted by what is substantially a frustrum of atriangle. The members 8 have a somewhat different shape, with rightangles 12 at their corners.

There is also along one free edge of the blank a pair of extensions 14,for the purpose of securing the blank in assembled position.

In order to assemble the blank, the parts 2 are folded inwardly out ofthe plane of the blank and the parts 4 upwardly from the ends of theparts 2, the free edges of the lowermost parts 2 being brought togetheralong with the free edges of the lowermost parts 4, after which theflaps14 are glued to the adjacent parts 2 and 4 so as to secure the blank inthe condition shown in FIG. 2. In this, it will be noted that thecorners 12 of the parts 8 are at the corners of a square, which squarehas substantially the area of the interior of the box in which theresulting pyramids are to be fitted.

The box itself has side walls 16 forming a closed container, innerflaps18 in which are formed cutouts providing a hexagonal opening 20, hingedalong the lines 22, and outer flaps 24 hinged along the lines 26.

The box is also provided in one of the side walls, that is, one of thewalls parallel to the axis of the wind, with a hole 28, in which fits atube 30 which may be of solid material or of rubber or of other similarflexible material. This tube is held in position by a pin 32 whichpasses through it, and which is held against the wall 16 by a sheet 34of cardboard or the like which is glued onto the face of the wall 16 inwhich the tube is mounted.

The wind itself is indicated at 36. It is a universal wind with a radialopening of its central axial opening, such as is described in the Taylorpatents referred to above.

The assembled blank shown in FIG. 2 is secured in the box in a positionin which the corners 12 coincide with the corners of the box, byengaging the two flaps 6, which are opposite each other, beneath the endportions 18a of one of the inner flaps 18, this flap being in raisedposition, and then swinging the flap and the pyramid-forming memberinward while inserting the end 18a of the other flaps 18 under the outerhalf of I flap 8. The condition then is that the parts 6 of thepyramidforming member lie beneath the ends 18a of the flaps 18 while theparts 8 of the cone-forming member overlie the flaps 18. The outer flaps24 are then folded over and secured, and assembled by glue or the like.7

The package then has the form shown in FIG. 4.

In assembling the package, one of the guide members is inserted in themanner just described. The wind is then placed in the package, with thelower pyramid extending into its. axial opening. The tube 30 is insertedinto the radial opening of the package, and the inner end of thematerial is brought out through the tube 30 to the outside of thepackage for withdrawal. The upper pyramid-forming member is thenassembled in the manner described previously, and is secured in positionby securing the flaps, 24.

The package is then ready for shipment.
